BELL-OPERATING DEVICE.

Specification of Letters Patent.

Patented Feb. 6, 1917.

Application filed March 30, 1916. Serial N 0. 87,740.

To all whom it may concern:

Be it known that I, WLADYSLAW SAK, a subject of the Emperor of Austria-Hungary, residing at Chicago, in the county of Cook and State of Illinois, have invented certain new and useful Improvements in Bell- Operating Devices, of which the following is a specification.

This invention relates to new and useful improvements in bell operating devices.

The primary object of the invention is the provision of a motor driven actuator for a bell tongue or clapper whereby the bell is loudly sounded whenever the motor is started in operation. 7

A further object of the device is the pro vision of an electrically operated clapper actuator having suitable adjustable connections and being arranged for preventing any muflling of the bell by reason of a contacting of the clapper therewith.

A still further object is to provide connecting means that is easy and inexpensive to construct and adapted to be operatively connected between the clapper of any ordinary bell and a usual form of electric motor arranged at a distant point with respect thereto for actuating the bell whenever desired.

With these general objects in view and others that will appear as the nature of the invention is better understood, the same consists in the novel combination and arrangement of parts hereinafter fully described, illustrated in the accompanying drawings and then claimed.

In the drawings forming a part of this application and in which like designating characters refer to corresponding parts throughout the several views: Figure 1 is a side elevation of the device with a portion of the building within which the same is assembled partially broken away and partly illustrated in vertical section. Fig. 2 is a side elevation of the hell with the clapper at one extremity of its stroke. Fig. 3 is a similar view with the clapper positioned at its opposite extreme, and Fig. 4: is a sectional View taken longitudinally of the clapper rod.

It will be understood that the device is designed for operatively swinging the clapper of any gong or hell of the usual depend ing form such as the bell 10 rigidly mounted beneath a support or beam 11 and arranged above the floor such as 12 of a building 13.-

ter by means of a belt 19 running over the wheel 17 and also over the pulley 20 of the said motor. A similar slightly larger wheel 21 is arranged above the wheel 17 upon the floor 12 and is connected by means of a belt 22 with a pulley 23 of the shaft 24; upon which the smaller wheel 17 is secured. It will be thus evident that by stopping and starting the motor 15 the wheel 20 may be controlled at the will of the operator.

A pitman or connecting rod 25 is attached between the wheel 21 and an extension 26 of the clapper 14, the said rod being formed in two parts 27 and 28 having their inner ends overlapping and provided with slots 29 for accommodating lock bolts 30 rendering the said rod adjustable in length. The free end of the rod portion 27 is pivoted as at 31 to the wheel 21 while the opposite end of the rod 25 is flexibly and elastically connected to the free end of the clapper extension 26 by means of a coil spring 32 attached to such extension and also to the free end of the rod portion 28.

From this detailed description of the device, it will be readily apparent that by controlling the operation of the motor 15 by a suitable switch (not shown) located at any desirable distant point the clapper 14: will be oscillated by the wheel 21 and rod 25 so as to contact the clapper alternately at the opposite sides of the bell, as illustrated in Figs. 2 and 3 of the drawings. The spring 32 affording a flexible and resilient connection between the operating rod and clapper allows the latter to engage the surface of the bell in the ringing operation and to thereafter rebound upon the vibrating of the bell preventing the clapper from mufiling or deadening such vibrations and providing loud alarms being sounded whenever the pivotal connection point 31 of the wheel 21 reaches a point substantially in the same horizontal plane as the axle 33 of the wheel 21 and at opposite sides of the axle. The motor 15 being operable under control of a distantly positioned switch, it is only essential that the motor 15 be directly operatively connected to the wheel 21 in ordinary cases, but the present plurality of wheels, pulleys and belts allows the motor 15 to be positioned at some distance beneath the bell 10, while by increasing the number of such elements the motor may be placed as far away from the bell as desired, while obviously, the operating pulley 20 might be operated manually such as by a crank (not shown) if desired.

\Vhile the form of the invention herein shown and described is what is believed to be the preferable embodiment thereof, it is nevertheless to be understood that minor changes may be made in the form, propor- Gopies of this patent may be obtained for tion and details of construction without departing from the spirit and scope of the invention as hereinafter claimed.

Vhat I claim as new is A bell ringing device including the combination with a rigidly mounted bell having a swinging clapper pivoted therein, of a rigid VLADYSLAJV SAK.
